Why is RSPAN not sending all packets?

Question

Cisco

I previously asked a question on cisco. The solution was to move the "listening" equipment to another location and found a separate cisco for it in the warehouse.
But I didn't get rid of my problems.
It costs Cisco 2960 from it 3 ports go to RSPAN Vlan
I did something like this
(config)#vlan 3113
(config-vlan)#remote-span
(config-vlan)#exit
(config)#monitor session 1 source interface fa0/25
( config)#monitor session 1 destination remote vlan 3113
It looks like this now - Cisco1_2960(vlan 3113 trunk to uplink)-extreme(vlan 3113 trunk)-extreme(vlan 3113 trunk)-cisco(vlan 3113 trunk)-Cisco2_2960(vlan 3113 just on the switch)
Further in Cisco 2
(config)#vlan 3113
(config-vlan)#exit
(config)#monitor session 1 source vlan 3113
(config)#monitor session 1 destination interface interface gi0/1 I
see traffic but not all. in what there can be a trabla?
UPD. Understood. For some reason, he did not want to send all traffic when it was indicated to send everything (both tx and rx), but if you specifically specify tx or rx, and not both (if you do not specify anything, both are automatically set) there are no problems. However, due to the fact that I would see all the packages I need (sip) - I had to add an uplink to the world.
